Shortly after getting my driver’s license, I stupidly merged onto a road with a 40 mph speed limit without looking left.
A car was coming right towards my driver’s side door. The driver of the other car made their brakes squeal (this was before ABS). Right before they would have hit me and probably killed me (this was before airbags), they released their brakes, swerved around me, and kept going.
It was some really impressive driving, and it likely saved my life.
